Is the jury still out?
William Broad responds:

in Science magazine last summer, a dozen or so scientific papers
have been presented, both for and against the fossil-life hypothesis. Richard
Zare, a chemist at Stanford University who is one of the original authors,
recently said that the new supporting evidence that has been gathered slightly
